DIE.

Application filed October 31, 1924. Serial No. 746,944.

To all whom it may concern: I

Be it known that we, HERBERT J. lVoonALL and Emmi: B. RICHARDS, citizens of the United States, residing at Grosse Pointe 5 Shores and Detroit, respectively, county of Wayne, State of l\1ichigan, have invented a certain new and useful Improvement in Dies, and declare the following to'be'a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying d'raw-. ings, which form a part of this specification. Our invention relates to an improved die intended particularly to be used in the cutting of apertures through cardboard or other material in connection with which it may be suitably employed. 7

Our invention is here illustrated in a die of the form required to punch circular openings but obviously may be so constructed as to form an" opening of any desired shape. It-is of such a character that when employed in-a suitable press or other power machine, the separate cuttings of the die are discharged therethrough without clogging the exhaust passageway through the die, thereby permitting successive cutting opera tions of the machine to be carried on rapidly and uninterruptedly. I

'An object is to provide a die as above set forth provided with a discharge outlet therethrough for the cuttings of the die adapted to cause the punched out portions of material to pass freely through the outlet for dis charge therefrom.

A further object 18 the provision in, a die of the kind above described of an outlet through the die for the cuttings .thereof, which outlet has a side discharge communithrough the Pr vided harge passageway without clogging. or amming up such pasageway. i

A meritorious type of construction is the provision in such a die of a channeled base member within the face of which is removably and preferably eccentricall'y mounted a cutting die having an opening therethrough die.

which we prefer totaper outwardly, which opening 1s provided with an outwardly pro- JGClllIlg peripheral cutting edge that terminates at the opposite end within the channel of the base for the discharge of the cuttings of the die thereinto to pass out through such channel, the discharge pasa'geway through said die being provided with means to guide the individual cuttings of the die to exhaust through the channel of-the base thereof.

Other objects and advantages of our invention will appear more fully from the following description of the embodiments thereof shown in the accompanying drawing and defined in the claims.

In the drawings:

Fig. l is a fragmentary elevationof a die board within which our improved die is mounted.

Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1.

"Fig.

Fig. 4 is a fragmentary vertical sectional view of a modified form of our improved die.

Our improved die is here shown as mount ed within a built up laminznzed. die board 10 which in turn is seated within a hollow press plate 12. Thedie comprises a base member 14 having a channel 16 extending across one side thereof. This base member is here shown as square. The base has a suitable opening 18 to removably receive a cutting die; in Fig.4 this is shown as a pressed fit while .in'Fig. 2 the cutting die 'is threaded into the opening in the base. This opening terminates within the channel thereof of the base, and is preferably positioned eccentri cally of the base. p

Removably mounted within this opening 18 is a cutting die 20 which has a flange portion 22 adapted to abut the outer face of the base member. This cutting .die is hollow having an opening 2& extending through the die and terminating at its outer end in a peripheral cuttingedge 26 that projects outwardly beyond the face of the -flange 22 andterminating at its inner end within the channel of the" base. In the drawing we have an opening circular in cross section. lVe prefer to taper the opening'outwardly as illustrated. j The discharge passageway through the die is so ccnstructed as to cause the cuttings of the die to pass therethrough withoutjam- 3 is a side elevation of our improved trated a construction employing a pin 28 extending transversely across the channel 16 rearwardly and at one side of the opening through the cutting die.

Our improved die is particularly adapted for use in connection with the piercing of apertures through cardboard panels, and is here shown as seated directly upon the plate 12 of the press and mounted within the die board 10. Due to the eccentric positioning of the cutting die within the base when the board is made up with the provided opening for the die, it will be seen that the location of the cutting die may be changed within certain limits by varying its position within the provided space in the board.

In the operation of the device, the sheet of material to be pierced is placed upon the die board and an impression plate carried by the machine but not shown in the drawing forces the material against the die board, thereby causing the cutting edge of the die to pass through the material to pierce the desired opening therein. The punched out portions of material enter the opening 24 of the cutting .die. Successive cutting operations crowd these punched out portions or discs through the passageway 24 to enter the channel 16. As a disc leaves the opening 2 1, it is engaged at one side by the slide 29 and the disc tilts inwardly at the bottom away from the succeeding discs and is caused to move through the channel 16 and through the outwardly flaring opening 30 of the die board to be discharged therefrom. In the construction shown in Figs; 2 and 3 the discs areengaged by the pin 28 and tilted as described and made to pass out through the discharge passageway as heretofore set forth. 7

What we claim is: I 1. In combination, a press plate, a die boa-rd seated thereon, a hollow die mounted in the board seated upon the plate, said die board provided with a discharge for outtings of the die, which discharge leads from the rear of the die opening through the board.

2. In combination, a press plate, a die' board seated thereon, a die assembly com prising abase moimted 1n the board and having a channel at the rear communicating with a discharge opening leading to the face of the board and a hollow cutting die mounted in such base terminating at the rear to discharge within said channel.

3. In combination, a press plate, a die board seated thereon, a die mounted in the board and provided with an opening therethrough having an outer peripheral cutting edge and terminating at the rear in an angular passageway for cuttings of the die that communicates with an outlet for said outtings through the die boardto the face thereof.

4. In combination, a press plate, a die board seated thereon, a die assembly mounted within the board comprising a channel base seated upon the press plate and a cutting die carried by the base and having an opening therethrough terminating in the channel of the base for the discharge of cuttings of the die therethrough, said die board provided with an outlet for the cuttings oi the die which leads from the face of the board to the rear of the opening through the cutting die. 7
